CAR-WHEEL CLAMP "WITH JACK BASE ATTACHED.

Application filed. May 31,

T 0 all whom it may concern:

Be it known that I, HARRY E. BnoNsoN. a citizen of the United States. residing at Mineral, in the county of Lewis and State of \Vashington, have invented certain new and useful Improvements in Car-\Vheel Clamps with. Jack Bases Attached; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a car wheel clamp with jack base attached primarily dewhen it is desired to lift the journal boxes of railway car wheel axles in order to remove or replace their brasses or bearings.

Aside from the invention generally aiming to improve and render more efficient and durable existing constructions of this general type, and yet maintain the cost of manufacture at the minimum, it is an object to provide a novel clamping member or lever and post mounting it in combination with. novel means to position and maintain the clamping member in operative position with respect to the car wheel.

Various additional objects and advantages will become apparent from. a consideration of the description following taken, in connection with accompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a View illustrating the invention in side elevation and in use in connection with a bearing-lifting jack, parts of railway rolling stock and a rail, such parts and rail being shown in section;

Figure 2 is a view in end elevation of the wheel clamp and jack base, the wedge key being shown in position to hold the jaw against upward movement;

Figure 3 is asimilar view with the exception that the wedge key is shown in retracted position;

Fig. a is a Figure 5 is sectional view ure 2.

Like reference characters designate like or similar parts in the different views.

The invention is primarily practised in. connection with wheels of railway rolling stock, either freight or passenger, and to facilitate an understanding of the invention plan View, and

a substantially central vertical taken on the line 5-5 of Fig 1923. Serial No. 642,553.

parts thereof have been, fragmentarily illustrated in the drawings. For instance A designates a railway car axle, B a wheel journaled thereon and C a journal box associated with the wheel and axle. \Yheel B travels ona rail D.

In carrying out, the, invention, a suitable base is provided as at 10 having a post or upright 11 thereon, preferably integral therewith and cast in a single piece. The base 10 is relatively large so that it may constitute a support for a jack or appliance E operable to lift thev bearing C. This base may have an'opening substantially centrally therethrough as at 13 so as to reduce weight.

Post 11 may be substantially solid or hollow as preferred and is provided with a recess 14: in which a clamping lever or jaw 15 operates. Jaw 15 extends beyond one side of the post so as to, overla a portion of the wheel. B for instance as shownv in, Figure 1 at the rim. 6. Jaw 15 has two or more bolt openings 16 .therethrough at the same end and which may be selectively entered by a pivot member 17,, preferably in the form of a removable bolt. The outer sides of the post 11 about said bolt is, preferably reinforced by bosses as at 18.

Any suitable means is. used to secure the jaw against upward or pivotal movement after it has beenv engaged with, the wheel B and may essentially consist of a wedge key 19. A suitably reinforced bracket 20 is secured as at 22 to, the post 11. This bracket has a central opening or slot 23 in line with the recess 14.- to accommodate operation of the jaw 15,. The brackets on opposite, sides of the slot 23 have outwardly offset loops 2 1 between. which and the adjacent face of the post, the lock key 19 is adapted for sliding movement. The lower or inclined edge of the lock key 19 directly bears on the upper edge of the jaw 15 and the last mentioned edges are preferably beveled as shown in order to afford more intimate contact. The upper longitudinal edge of the lock key 19 is substantially straight and adapted to abut shoulders 25 connecting the loops 24 to the remainder of the bracket.

Projecting from, the lock key adjacent its smaller end is a retaining pin 26. One loop 24 is outwardly offset in order to provide a groove 27 through which the pin 26 may be drawn and the other loop 24; is provided with a notch 28 adapted to be entered by said pin upon withdrawing movement, to the end that the key may be effectively moved from across the recess 14 and slot 23 in order to permit vertical movement of the aw 15. At the same time, the engagement of the pin 26 in the notch 28 prevents detachment of the key from the device and thus minimizes the chances of loss thereof.

In use, the base 10 rests on the ground or suitable support such as a block 29 and the jaw 15 at its free end is applied to the wheel B as at the rim Z) in Figure 1, while the looking key 19 is withdrawn or retracted to the extent permitted by notch 28 and pin 26. The lifting jack or device E for the bearing C is adapted to rest on the base 10 and while in that position be operated to lift the bearing C. Either before positioning the jack E or after positioning it, the lock key is applied to the position shown in Figure 1 by sliding movement so that its upper edge will bear against the shoulders 25 and its lower edge will wedge against the upper edge of the jaw 15. When in this position, the wheel B is clamped against the rail D and thereupon the jack E may be operated in order to lift the bearing C for the purpose desired.

It is to be understood that the parts of the device may be made of any suitable material and that they are usually made of any preferred metal and no limitation as to size of the parts is to be inferred since they will vary according to conditions.

Various changes in the details may be resorted to without departing from the spirit and scope of the invention.

l Vhat is claimed is 1. A device of the class described having a post, a jaw pivoted to the post and engage able with a wheel to secure the same against elevation from its track, a bracket on the post having a slot through which the jaw extends, the bracket having offset loops on opposite sides of the slot, shoulders extending inwardly from the loops, and a key slidable intermediate the loops and posts in engagement with said shoulders and said jaw.

2. A device of the class described having a post, a jaw pivoted to the post and engageable with a wheel to secure the same against elevation from its track, a bracket on the post having a slot through which the jaw extends, the bracket having offset loops on opposite sides of the slot, shoulders extending inwardly from the loops, and a key slidable intermediate the loops and posts in engagement with said shoulders and said jaw, a retaining pin on the key, and one of the loops having a groove through which said retaining pin may pass, said pin being adapted to abut the other loop and thereby prevent movement of the key from the bracket.

8. A device of the'class described having a post, a aw pivoted to the post and engageable with a wheel to secure the same against elevation from its track, a bracket on the post having a slot through which the jaw extends, the bracket having offset loops on opposite sides of the slot, shoulders extending inwardly from the loops, a key slidable intermediate the loops and posts in engagement with said shoulders and said jaw, one of the loops having an offset portion to provide a groove, the other loop having a notch, and said key having a retaining pin adapted to pass through said groove to engage said notch through retracting movement thereof to prevent displacement of the key.

4. A device of the character set forth including a post having angularly related slots, a jaw pivoted to the post within one of said slots, and a wedge key slidably mounted in the other slot and engaging the aw.

5. A device of the character set forth including a post having angularly related slots, a jaw provided adjacent one end with spaced openings and having said end disposed within one of the slots, a bolt passing through the post and one of the openings to pivot the jaw to the post, and a wedge key slidably mounted in the other slot and engaging the upper side of the jaw.

G. A device of the character set forth including a post having angularly related slots, a jaw pivoted to the post within one of said slots and provided with a laterally inclined upper edge, and a wedge key slidably mounted in the other slot provided with a laterally inclined lower edge engaging the upper edge of the jaw.

7. A device of the character set forth in cluding a post having angularly related slots, a jaw pivoted to the post within one of said slots and extending downwardly and forwardly beyond the post, the upper edge of said jaw being laterally inclined, and a wedge key slidably mounted in the other slot of the jaw and provided with a laterally inclined lower edge engaging the upper edge of the jaw.

In testimony whereof I affix my signature in presence of two witnesses.
